The RCBS Trim Mate Chamfer Tool, Carbide (RCBS part no. 90384) is a replacement cutter for the RCBS Trim Mate case prep station. RCBS built it with a carbide tip specifically so it chamfers case mouths cleanly without dulling the way a plain steel cutter would after repeated use on brass. Reloaders running a Trim Mate through high case volumes reach for this when the factory-installed cutter finally wears out, since the carbide tip is built to outlast it by a wide margin.

Key Specifications

• Chamfer tool is a dedicated RCBS Trim Mate cutter for the chamfer station, not a universal or multi-purpose bit.
• Replacement cutter is designed to swap directly into an existing RCBS Trim Mate case prep station.
• Carbide-tipped construction is what lets this cutter hold an edge far longer than a plain steel tip.
• Cuts clean and chamfers case mouths cleanly case after case, which is the whole point of upgrading to a carbide tip.
• Tool length measures approximately 6.9 inches, sized to fit the Trim Mate’s cutter mount.
